Acrylic paint VALLEJO 73.818 Brown 40 ml — single bottle

VALLEJO 73.818 Brown 40 ml is a single bottle of water‑based acrylic paint from the Weathering FX/Engine Effects family, formulated for modelling, miniatures and craft applications. The 40 ml pot contains a brown shade designed to depict engine soot, grime and other weathering effects on vehicles, armour and dioramas. The acrylic formulation offers consistent coverage, easy thinning for airbrush or brush use, rapid drying for many techniques and compatibility with mixed‑media hobby workflows. Tools wash clean with water and soap.

Advantages

This brown acrylic paint uses permanent pigments and water‑based resins to provide stable colour and predictable behaviour during layering and weathering. It is suitable for both brushwork and airbrushing when thinned, dries quickly in thin applications, and allows further manipulation in many cases to achieve streaking, staining and soot effects. Non‑flammable and solvent‑free formulation simplifies studio safety and cleaning.

Suitable for

• Creating engine soot, oil stains and grime on vehicle and aircraft models
• Weathering armour, tanks and military miniatures
• Detailing dioramas, railway rolling stock and industrial scenes
• Layering and glazing in miniature painting and scale models

Key specifications

• Volume: 40 ml
• Colour family: Brown — formulated for soot and engine grime effects
• Base: Water‑based acrylic resin with permanent pigments
• Application methods: Brush and airbrush (thinning recommended for airbrush)
• Drying behaviour: Rapid drying for thin layers; thicker deposits may require longer curing
• Cleanup: Water and soap

How to use

Shake the bottle well before use to homogenize pigments. For brush application, apply thin layers and allow to dry between coats to build up realistic soot and grime. For airbrushing, thin the paint with appropriate acrylic thinner or water until it reaches the recommended viscosity for your airbrush, and test on a scrap surface before applying to the model. Many techniques benefit from applying the colour sparingly and then manipulating wet or semi‑dry layers with a damp brush, cotton swab or soft cloth to create streaks, stains and blended transitions. Allow thicker applications to dry fully before further handling.

Usage recommendations

Use on primed or previously painted surfaces compatible with acrylics. Test compatibility with varnishes and other weathering products on a small area. Store the bottle upright, tightly closed and protected from extreme temperatures. Refer to Safety Data Sheet for detailed safety information.
